more particularly, to apparatus and a method for achieving suchfastening by placing a bead of adhesive over the tail on the winding andto the resulting winding with the tail releaseably fastened thereon.

When bobbins or spools of yarn or other strands are wound commercially,it is necessary to secure the end of the yarn trailing from the lastapplied turn so that the yarn does not unravel during or afterpackaging. This trailing end is referred to as the tail of the winding.It has been the practice in winding bobbins of thread to tuck the tailunder one of the previously applied turns to hold it in place. Even whenbobbins are wound on otherwise fully automatic winding equipment, thepractice in the industry has often been to hire personnel to do thistucking of the tail by hand. This particular operation has long beenrecognized as perhaps the most inefficient step in the entire process ofwinding bobbins of thread. Automatic tucking devices have recently beenmade available to eliminate the manual operation but they result in ahigh percentage of rejects and in addition they are complicated deviceslacking in versatility.

The problem of how to secure the tail of a winding arises not only withrespect to bobbins of thread but also in the winding of many other kindsof non-metallic and even metallic filaments. While reference is madeherein to strands of yarn, it is to be understood that many otherfilamentary materials are also contemplated. The present invention hasparticular application, however. to the fastening of winding tails inautomatic yarn winding machines which produce one or more windings oneach of a plurality of cores simultaneously.

SUMMARY OF THE INVENTION In broad terms, the invention is applicable toyarn winding apparatus wherein a core is rotated at a first station toform a winding of yarn thereon. Gripping means carries the winding to asecond station in such apparatus, and a cutter severs the yarn betweenthe stations to leave a tail on the winding. Automatic tail fasteningmeans are provided in apparatus of this sort comprising yarn holdingmeans for locating the tail in a given position on the winding at thesecond station. An adhesive ejector is displaceable adjacent the secondstation, and it includes a nozzle out of which a bead of adhesive can beejected Indexing means are included for aiming the nozzle of the ejectorwhere the tail is held on the winding. The ejector is actuatable toeject a bead of adhesive from the nozzle unto the winding over the tailto fasten the tail in place when the adhesive sets. Means are alsoincluded for opening the gripping means to release the winding after theadhesive bead sets and for returning the gripping means to the firststation.

The invention also provides a method applicable to the formation of awinding of yarn wherein a tail is left on the winding. The method is forreleaseably fastening the tail and it comprises holding the tail in agiven position on the winding, placing a bead of adhesive over the tailon the winding, and setting the adhesive to fasten the tail in place.

A product is also provided by the invention, namely a winding of yarnhaving an end tail and means for releaseably fastening the tail in placecomprising a bead of adhesive located over the tail on the winding.

machine to which the invention principally relates is illustrated in thedrawings since the remaining structure and function characteristic ofsuch machines are well known. Some of the standard elements of anautomatic winding machine not shown are the supply packages of yarn, thetension-controlling means for maintaining the desired tension in theyarn strands, as they are directed to the spindles, the magazine holdinga supply of cores about which the bobbins are to be wound, theassociated means for placing those cores on the spindles, and the hopperinto which the completed bobbins are discharged. In addition, nodetailed description is given herein of the various drive means,controls and the like which permit the apparatus of the invention tooperate in a fully automatic manner. Automatic winding machines of thetype contemplated are manufactured, for example, by CezomaTestielmachinefabrieken N.V.,

Uden, Holland substantially as shown in their brochures 66-04-04 and71-04-01 and particularly their type EK-A4N-3 machine.

Referring first to FIGS. 1 through 5, the machine includes a frame 20 onwhich are rotatably mounted four spindle drive shafts, 21, 22, 23 and24. These shafts are horizontal and parallel to one another and aredriven by suitable drive means. The shafts each have a drive headmounted thereon, drive heads and 26 for drive shafts 21 and 22respectively being illustrated in FIG. 1. Each of these drive heads ispaired with a coaxial tailstook and spindle which are not only rotatablebut also translatable in and out with respect to the drive head. Atailstock 27 and its spindle 29 are associated with the head 25 andtailstock 28 and its spindle 30 are associated with the head 26, all ofwhich is visible in FIG. 1. Only spindles 31 and 32 are shown inconnection with the drive shafts 23 and 24 respectively. The four driveheads hold respective drive spindles 29a to 32a which are coaxial withand opposed to the associated tailstock spindles 29 to 32.

As shown in FIGS. 3 and 4 particularly, the drive spindle 29a is formedwith a nose 33 defining a shoulder on which notches 34 are inscribed. Anose 35 is also formed on the opposite tailstock spindle 29. Thesefeatures are also present on each pair of drive and tailstock spindles.By well known means not shown in the drawings, four paperboard tubesknown as cores 36-39 (see FIG. 1) are carried from a nearby supplymagazine by means of a slide and brought into position coaxially betweenthe respective pairs of spindles 29 -29a, 30-30a, 31-3la and 32-32a whenthe tailstock spindles 29-32 are retracted. The tailstock spindles 2932are then translated axially toward their associated drive spindles29a-32a (upwardly as shown in FIG. 1 and to the left as shown in FIGS. 3and 4) to grip the cores 3639 in place as shown in FIG. I. Thesefunctions and mechanisms are well known in the art.

Referring to FIG. 1, guide eye assemblies are shown for properlydirecting strands of yarn from a supply source onto the cores to bewound into windings. All four pairs of spindles are provided with thesame guide eye assemblies though not all are visible in the drawings. InFIG. 1, guide eye assemblies 40 and 41 are shown in association withspindles 31-3Ia and 32-32a respectively. In FIG. 2, a guide eye assembly42 is shown in association with the spindle 2929a. Each quide eyeassembly includes three ceramic eyelets through which three respectivestrands of the yarn are carried onto the associated core. In FIG. 2,strands 43a, 43b and 430 are shown being directed unto the core 36 toform three windings on the one core. In this embodiment of theapparatus, three such windings are formed on each of the four cores36-39. v

The guide eye assemblies are mounted in pairs on two guide eye shafts 45and 46. The guide eye assemblies 40 and 41 (see FIG. I) are hinged ontraverse shafts 45 and 46 which are traversed by the usual cam mechanismwell known to the art. The guide eye assemblies can be lifted by meansof an air cylinder 47 which acts through a lever 48 to rotate a shaft49. Pairs of arms 50-5011 and 51-5111 are fastened to an extend from theshaft 49 so that upon rotation of the shaft 49 the pairs of arms move inan upwardly directing lifting the guide eye assemblies up from or downtoward their associated cores.

Mounted on the frame 20 of the machine is a crank arm 52 connected atone end to a carriage 53 designed to move in and out with respect to thedrive spindles when the arm 52 is operated back and fourth. The carriage53 supports four Y-shaped thread forks associated with the respectivepairs of spindles. The tread forks 54 and 55 are both visible in FIG. 1associated with the respective spindles 29-29a and 30-30a. By

means of the crank arm 52 and carriage 53, these thread forks can bemoved between a retracted position as shown in FIGS. 1, 2 and 5 and anadvanced position as shown in FIGS. 3 and 4. In the advanced position,the thread forks pick up the three strands of yarn associated with eachpair of spindles and pull the three strands together adjacent theassociated drive spindle for reasons described hereinafter. The drivemeans and linkage for operating the crank 52 and the associated threadforks is well known in the art and is therefore not shown in thedrawings.

Also included are a pair of thread arms 56 and 57 which swing on theframe 20 about respective pins 56a and 570 all as shown in FIG. 1. Thearm 56 an be pivoted 90 from its withdrawn position shown in FIG. 1counterclockwise under the spindle 29-2911 and 3030a to the closedposition shown in FIGS. 4 and 5 The movement of the arm 57 is inclockwise direction under the spindles 31-31a and 32-32a in much thesame manner. When the thread arms are moved in this fashion, they engagethe two associated sets of three strands and pull them in under thedrive spindles into a cutting device, one of which is shown in FIGS. 2to 5 as cutter 58. The structure and function of such means for severingthe sets of three strands are also known and are not therefore shown anddescribed herein in further detail.

Adjacent each of the respective drive spindles 29a32a are air jetsdesigned to direct a blast of air toward the threads after they havebeen severed by the cutting devices 58. Air jets 60 and 60a are shown inFIG. 1 associated with spindles 29-29a respectively, and the air jet 60is also visible in FIGS. 2 to 5.

Pivotally mounted on the frame 20 of the machine is a shaft 61 whichcarries two arms 62 and 62A (see FIG. 6) which in turn support a flatplate 63. An air cylinder 64 is linked between the arm 62 and a plate 65fixed to the frame 20 of the machine to move the plate 63 between itsuppermost position as shown in FIG. 2 and its lowermost position asshown in FIG. 3. The uppermost and lowermost positions of FIGS. 2 and 3are determined by stops 66 and 66a respectively on the plate 65 of themachine which engage surfaces 67 and 67a respectively fixed with respectto the plate 63. Between these extreme upper and lower positions, theplate 63 can be indexed with some precision by a second air cylinder 69having a piston rod 70 adapted to engage the surface 67a and move thearm 62 counterclockwise as shown in FIG. 4.

Referring particularly to FIGS. 6 and 8 and also to FIGS. 4 through 5,it will be seen that an air cylinder 72 is supported by the plate 63. Apiston rod 73 of the air cylinder is linked to a pin 74 extending from ablock 75. As shown in FIG. 8, the pin 74 also extends from the side ofthe block 75 opposite the piston rod 73, and has mounted on thatopposite extension a first pair of spacers 76 which are designed to movefreely back and forth in a slot 77 formed in a slide 78. Beyond thespacers 76, the shaft 74 extends through a close fitting hole 80 in asecond slide 81 which is disposed between the first slide 78 and theplate 63. Beyond the second slide 81, the pin 74 carries another pair ofspacers 82 which are adapted to move freely back and forth in a slot 83formed in the plate 63.

A block 84 on the first slide 78 carries a gripper support 86. Ablock 87on the second slide 81 carries a gripper support 88. The grippersupports 86 and 88 are associated with the spindles 29-29a. In likemanner, a block 89 on the first slide 78 supports a gripper support 90and a block 91 on the second slide 81 supports a gripper support 92. Thegripper supports 90 and 92 are associated with the spindles 30 and 30a.As shown in FIG. 6 another set of blocks and gripper supports similarlymounted on the slides and associated with the spindles 31 and 31a and afourth set of blocks and gripper supports is likewise located withrespect to the spindles 32 and 32a.

The apparatus associated with each of the four pairs of blocks 8487 etc.and gripper supports 86-88 etc. can be described with respect to thefirst pair, i.e. that associated with the pair of spindles 29-29a. Asshown in FIGS. 6 and 12 in relation to the spindles 29 and 29a, thetypical mount 94 is rotatably supported on a bolt 95 fixed to the plate63. Extending from the mount 94 is a rod 96 which projects through aneyelet 97 secured to the second slide 81. AT it upper end, the rod 96 isconfigured in the manner shown in FIG. 7 to support three threadcentralizing fingers 98, 99 and 100 (see also FIG. 2).

A link 102 is provided as shown in FIG. 6 to connect to the first slide78 by pin 103 at its lower end and to the second slide 81 by a pin 104at its upper end. The center of the link 102 is pivotly connected to theplate 63 by a third pin S equidistant from the pins 103 and 104.

When the air cylinder 72 is operated so that its piston rod 73 is movedto the left to the position shown in FIG.

6, the spacer 76 simply moves freely within the slot 77 in the firstslide 78. However, because the pin 74 is closely fitted in the hole 80in the second slide 81, the second slide 81 is thereby carried to theleft as shown in FIG. 6. The other end of the pin 74 carrying the roller82 merely moves within the slot 83 in the plate 63. As the second plate81 moves to the left, the link 102 is turned counterclockwise, thuscausing the first slide 78 to move a corresponding distance to the rightas shown in FIG. 6. Because the slides 78 and 81 move in equal andopposite directions, the respective pairs of gripper supports are alsocaused to move in equal and opposite directions. The gripper support 86connected by the block 84 to the first slide 78 moves to the right. Thegripper support 88 connected by the block 87 to the second slide 81moves to the left. As a consequence, the gripper supports close withrespect to one another. In doing so, the eyelet 97 on the second slide81 moves to the left as shown in FIG. 6 and causes the rod 96 with itsthread centralizing fingers 98-100 to move to the left to pull the setof three threads over to the left as shown in FIG. 6.

Bobbin grippers are located on the extremities of the gripper supports.As shown in FIG. 6 with respect to the spindles 29-29a, the grippersupports 86 and 88 carry corresponding bobbin grippers 107 and 108.These grippers are designed to clasp the set of three windings on asingle core as shown in FIG. .7. The left gripper 107 supports anelectrical wire 110 which comes in contact with the three associatedstrands when the centralizing fingers 98100 move those strands to theposition shown in FIGS. 6 and 8. By suitable circuitry, eleetric currentcan be passed through the wire 110 at the point in the cycle ofoperation when it is desired to sever the strands from their windingsand the respective tails.

Also supported by the plate 63 and moveable therewith is a suction hornassociated with each of the four spindles. Referring particularly toFIGS. 4 and 5, the suction horn 112 is supported on a bracket which inturn is mounted on the plate 63. The suction horn 112 has a mouth whichis positioned such that the associated set of three strands is laidacross it in a manner described hereinafter.

Turning now to FIGS. 3 and 9, a shaft 113 on the plate 65 supports aplate 114. Angular adjustments of position of the plate 114 can be madeby turning a small adjustment cam 115 located on a pin 116. The plate114 supports a cam motor 118 which by gears 119 and 120 is designed torotate three coaxial cams 121, 122 and 123. As shown in FIG. 9, the cams122 and 123 are designed to operate microswitches 124 and 125respectively. The cam 121 is a lift cam which turns through successivepositions shown in FIGS. 2 through 5 respectively.

Mounted about a shaft 127 on the frame 20 of the machine are a pair ofsupport blocks 128 and 129 shown most clearly in FIG. 9. The supportblocks 128 and 129 carry rods 130 and 131 respectively by adjustablespring-mounted screw connections illustrated in FIG. 9 which permit therods 130 and 131 to be moved in and out to various positions. The otherends of the rods 130 and 131 carry a frame 132 on which are mounted fouradhesive ejector nozzles 134 to 137 associated with the respectivespindles 129-129a through 132-132a. Electrical lead 138 to 141 extend tothe respective nozzles to maintain at the proper temperature an adhesivecomposition which is ejected out of those nozzles. Suitable means arealso provided for delivering a supply of hot flowable adhesive to-thesenozzles and for squirting beads of adhesive from the nozzles on signal.Such guns are well known to the art.

The operation of this automatic bobbin winding machine will be describedbeginning at the point in its cycle where cores 36-39 are mounted on therespective spindles and are rotating so that the three strands of threadare pulled downwardly through the respective guide eye assemblies toform three windings on each core. Referring first to FIG. 2, the aircylinder 64 is in an extended position so that the grippers 107 and 108are disposed at what can be called a first station to each side of thethree windings on the core 36. These three windings are motionless atthis point and fully formed with their last wrap in approximately themiddle of the traverse. The air cylinder 72 is then automaticallyoperated to cause its piston rod 73 to move to the extreme left positionas shown in FIG. 6, as a result of which the first slide 78 is moved tothe right and the second slides 81 is moved to the left as shown. Thiscauses the grippers 107 and 108 to close about the three windings on thecore 36. The spindles 29-32 are then withdrawn to the right from theposition shown in FIG. 2 to the position shown in FIG. 3. The aircylinder 64 is then actuated to lower the grippers from the firststation shown in FIG. 2 to a second station as shown in FIG. 3. Thethread forks 54 move from their retracted position shown in FIG. 2 totheir advanced position shown in FIG. 3 at this point. The thread arms56 and 57 are then turned about their respective pins 56a and 57a todirect the strands of yarn into operative engagement with the cuttingdevice 58. This movement of the thread arms is from the position shownin FIG. 3 to that shown in FIG. 4.

The following operations are described in relation to the windings foundon the spindles 29-29A, but the operations are the same on the otherfour windings as well. At this point with the grippers 107 and 108closed, the thread centralizing fingers are in the FIG. 7 position andinsure that the strands lie across the mouth of the suction horn l 12and directly against the grooves 34 adjacent to the nose 33 on the drivespindle 29 where the strands can readily be trapped by the next corewhen it is pushed into place on the spindles. The cylinder 69 is thenoperated so that it moves the arm 62 from the position shown in FIG. 3to that shown in FIG. 4. This causes the strands between the forks 54and the grippers to be slackened allowing the suction tube 1 12 to pullin a small loop of the strands as shown in FIG. 4 and hold the strandstight. The cutting device 58 is then operated to sever the strands justabove the arm 56. It is at this time that the guide eye assemblies lowerinto position adjacent the next core which by then is in place on thespindles and the spindles begin to turn. The thread fork 54 is alsomoved from its advances to its retracted position at the same time theguide eye assemblies are lowered. The lower cut end is immediatelysucked into the vacuum tubeto hold the tail of the strands tight. Theupper ends are blown by the jet 60 alongside the next core on thespindles, which at that point is mounted in place and rotating, so thatthose ends are wrapped under the next windings. The fingers 98 to 100are still engaging the yarn tails at this point and hold them closelyagainst the electrical wire 110. This condition of the apparatus isshown in FIG 5.

The thread arm 56 swings back to its starting position shown in FIG. 1as the adhesive application cycle begihs. During this cycle the lift cam121 raises the nozzles from the position shown in FIG. 3 to that shownin FIG. 4 where the nozzle 134 is correctly aimed at the lowermostwinding on the core. The cam 122 operates the micro switch 124 at thispoint causing a bead of adhesive to be ejected out of the nozzle 134,carry across the space separating the nozzle tip from the surface of thewinding, and impinge on that surface just above the point where the tailof that winding is located.

The axis of the windings is substantially vertical at this time. Becauseof the particular nature of the adhesive composition which will bedescribed hereinafter, the applied bead sags or gravitates very slightlydown across the surface of the winding to set when it is locateddirectly over the tail. The tail is thereby fastened firmly in place.After the first adhesive dot is applied, the lift cam 121 raises thenozzles to a second position where a head is similarly applied to themiddle winding of the core. Finally, after that is completed, the liftcam 121 raises the nozzles to a third position (as shown in FIG. 5)where a head of adhesive is ejected onto the last of the three windingson the core. There is still another lobe on the lift cam 121 whichraises the nozzles slightly above the last bead application position tobreak any adhesive that may string out between the nozzles and the lastwinding.

The cam 123 operates the switch 125 during this stage of the cycle tostart a timer for the trimming of the tails by means of the hot wire110. This timer is set to turn on the current momentarily so that thehot wire 1 burns through the tails and severs them. The removed sectionsof the strands are immediately sucked into the horn 112. Trimming of thestrand tails in this manner takes place at a point after the adhesivehas set.

A new set of three windings is in the process of being formed on anothercore all the while the grippers are carrying out these operations at thesecond station. The spindles are then halted with the traverse of theguide eye assemblies stopped at a point where the last wrap isapproximately centered in the middle of the traverse. The guide eyeassemblies are then lifted upwardly from their associated completedwindings by the arms 50-50a and 51-51a.

At this point, the cylinder 72 is operated to pull its piston rod 73 tothe right as shown in FIG. 6 and thereby open the grippers to releasethe fully formed windings so that they drop into a suitable dischargehopper. The thread centralizing fingers 98-100 are moved to a withdrawnposition at the same time. The air cylinder 64 is then operated to liftthe grippers back to the FIG. 2 first station position. The next set ofthree windings on a core is ready at this point so that the grippers mayclose about them and repeat the entire cycle.

As the product emerges directly from the automatic winding machine, itconsists of a core on which three windings 151 to 153 are supported asshown in FIG. 10. The windings have end tails 154 to 156 respectivelyreleaseably held in place by beads of adhesive 157 to 159 located overthe tails on the windings. To be formed into finished bobbins, the core150 is cut in two places between adjoining pairs of windings and thenfitted within flanges 160 and 161 as shown in FIG. I l.

The adhesive to be used for the tail fastening bead in accordance withthis invention is preferably of thermoplastic material. A standardcarton sealing adhesive such as Swift 625 manufactured by the SwiftChemical Company, a division of Swift & Company, Oak Brook, III., isespecially suitable. It is advantageous to add to such an adhesiveapproximately three percent by weight of a silicon dioxide thickenersuch as Cab-O-Sil, a trademark of the Cabot Corporation, Boston,Massachusetts. It is also advantageous to add to each pound of the basicadhesive two cubic centimeter of a wetting agent such as Triton, atrademark of the Rohm and Haas Company of Philadelphia, Penna. Thecomplete adhesive composition is chosen to be readily applied by anejector nozzle and to set quickly after a bead of it gravitatesdownwardly a predetermined amount subsequent to application to avertical surface. The material of the adhesive may also be paraffin orthe like though that is considerably more difficult to control in flowand setting properties.
